A Missionary's Memoirs: Mongolia Revisited, Isaac Smith

Undergraduate Honors Theses

This is my story. It is a very personal story, but one that I want to share with others. Although it takes place predominantly in Mongolia, it is not merely a story about Mongolia, or even the Mongolian people. It is not really even a story about me. What is it then? It is a story about faith and love. It is an attempt to better understand how the gospel of Jesus Christ intricately fits into people’s lives all over the world—even in Mongolia. It is a compilation of essays, of memoirs, of my experiences. It is a story about …

Exploring Consequences Of The Double Empathy Problem Across The Autistic Trait Spectrum: First Person Accounts, Cammy C. Peck

Theses and Dissertations

Historically, individuals on the autism spectrum were believed to have deficits in empathy. However, recent research suggests that empathy-related issues occur on both sides of the communication dynamic. This concept known as the Double Empathy Problem (DEP), posits that the perceived lack of empathy is not exclusive to autistic individuals; rather, neurotypical (NT) individuals also experience difficulty empathizing with autistic individuals (Milton, 2012). Milton et al. (2022) describes this as a "breakdown in mutual understanding". Such mutual misunderstanding can have adverse consequences for both autistic and neurotypical individuals. To our knowledge, no studies have directly examined these consequences in relation …

The Effect Of Personalized Profiles On Generating Customized Content In Artificial Intelligence Augmentative And Alternative Communication Devices, Rachel Johnson

Theses and Dissertations

With advancements in artificial intelligence (AI), several augmentative and alternative communication (AAC) devices have begun incorporating AI with the purpose of accelerating and improving message transmission for users. The results have shown that AI can significantly reduce a user's keystrokes, but the generated responses may lack personalization. The objective of this study was to investigate whether integrating a personalized profile containing user information enhances the perceived accuracy and personalization of AI generated messages. Various methods of collecting profile information and differing levels of information within the profile were evaluated. One hundred eighty-one neurotypical English-speakers with no history of language disorder …

Simulating And Designing Pyro Fx To Communicate A Hostile And Magical Environment, Rebekah L. Tran

Undergraduate Honors Theses

This thesis aims to document the fire FX work completed on this year’s senior capstone film, Love & Gold, for the BYU Center of Animation. The story of the film is brought to life with many different types of effects including snow, sparks, lava, rock shattering, magic, hair, cloth, and the topic of this thesis, fire. The film has three main fire simulation needs: torches, braziers, and fire traps. The FX team on the film created these with Pyro simulations. Pyro simulations are a common type of simulation supported by Houdini FX, the software program that BYU Animation primarily uses …

Strivers, Ambivalence, And The Implications Of Wholeheartedness, Kaia K. Hathaway

Undergraduate Honors Theses

In this thesis, I examine Harry Frankfurt’s account of the will and its implications for ambivalence, particularly in the context of moral striving. I begin by outlining Frankfurt’s hierarchical model of desires and his view that ambivalence represents a failure of agency. I then explore his proposed solution—wholeheartedness—which aims to resolve inner conflict by rejecting incompatible desires. Drawing on David Velleman and Justin Coates, I argue that Frankfurt’s view faces both agential and ethical challenges, especially for individuals engaged in upward mobility, or “strivers.” I suggest that the experiences of strivers—those who must navigate competing ethical commitments—pose a unique challenge …

Delaunay Keyer For Colorspace-Local Matte Extraction And Spill Suppression, Isaac J. Criddle

Undergraduate Honors Theses

Keying is a fundamental, common, and expensive problem in visual effects. It consists of two subtasks: matte extraction and screen spill removal. Today’s standard keyers often fall short on edge cases including unevenly lit screens, fine detail, and sky replacements. As a result, keying continues to be a laborious process requiring highly trained compositors and complex bespoke setups. Our method does not assume one single saturated screen color, allowing for more versatile workflows. The keyer functions by interpolating over a Delaunay tetrahedralization of user-given sample colors. We evaluate our method relative to the visual effects industry’s standard keyers on a …

Perceptions Of Spirituality And Of God: A Psychological Qualitative Study, Christopher E. Peck, Timothy B. Smith, Jamila Mastny

Faculty Publications

The majority of people living in the U.S. report that spirituality is an important part of their life that is influential to their well-being. However, individuals vary widely in how they conceptualize spirituality, which often stems from and overlaps with their conceptualizations of God or so-called “God image”. Examination of people’s experiences of spirituality and conceptualization of God can enable psychologists to improve their understanding of individuals’ core personal experiences. This study evaluates both spirituality and God image, as well as the relationship between these two constructs, using qualitative hermeneutic analysis of interviews with 63 adults (51% women, 49% men, …

How A Swiss Person Bought A Part Of The Russian Empire In California: Revisiting Johann August Sutter’S Purchase Of Fort Ross In 1841, David Aragai

Swiss American Historical Society Review

Today, Fort Ross is a State Historic Park along California’s Highway Number 1. It is about one hundred miles north of San Francisco on the wild, beautiful, and wind torn Sonoma Coast. Founded in 1812, Fort Ross was originally an outpost of the Russian Empire; the southernmost on the American continent and the one farthest away from the imperial capital, St. Petersburg. It was built with the intent to help feed the Alaskan colony, as well as to extract sea otters and other mammals from the surrounding waters due to their valuable fur.

The Effects Of Morphine, Thc, And Lsd On Synaptic Plasticity Of The Ventral Tegmental Area, Michael Von Gunten

Theses and Dissertations

The brain is an intricate network of neurons that communicate via synapses. Synaptic plasticity, which is the ability to strengthen or weaken synaptic connections, plays a key role in learning, memory, and reward learning. Disruptions to synaptic plasticity play a central role in addiction, particularly in brain circuits involved in reward and motivation. The mesolimbic reward system, which includes the ventral tegmental area (VTA) and its dopaminergic projections, is a primary target of drugs of abuse, including opioids and cannabinoids. However, the physiological consequences of combined exposure to opioids and cannabinoids and the potential for psychedelics to reverse drug-induced neuroadaptations …

The Earth's Voice: The Social, Spiritual, And Secular Justifications For The Earth's Freedom Of Expression, Ashley Tzeting Pun Eveson

Theses and Dissertations

The Earth's legal right to freedom of speech remains largely unexplored within the broader legal movement for the rights of nature, which emerged in the 1970s. While environmental law increasingly recognizes nature's rights to exist and thrive, as illustrated by legal rights granted to various natural entities--like the Whanganui River or manoomin rice--the Earth's ability to communicate remains underdeveloped. This study employs legal research analysis to examine the philosophical reasoning behind how social, spiritual, and secular frameworks justify the Earth's right to freedom of speech and expression. It explores legal guardianship, scientific data, Indigenous knowledge, and spiritual stewardship as valid …

Connecting With Our Creator: How Experiences In Nature Enable Closeness With God, Elsa Longhurst

Undergraduate Honors Theses

Experiences in nature allow individuals to connect with God powerfully. Many researchers have considered the benefits of nature (Fredrickson & Anderson, 1999; Louv, 2008; Unsworth et al., 2016), but few have studied the potential for nature to help individuals connect with Deity (Naor & Mayseless, 2020). The present study seeks to understand how nature can help people have a deeper connection to God, considering both vertical and horizontal spirituality (Krauss & Silver, 2021). Participants felt that spending time in nature strengthened their conviction that God is the creator of all things. Many participants shared that being outside allowed them to …

Insights Into Cortical Organization And Executive Dysfunction In Pediatric Traumatic Brain Injury, Madeleine Reading

Theses and Dissertations

Cortical gyrification is essential for cognitive development, yet its relationship with executive functioning (EF) in pediatric traumatic brain injury (TBI) remains unclear. This study examined whether children with TBI exhibit atypical cortical folding in EF-related regions and whether these differences relate to EF performance. Using FreeSurfer 7.1.1, we analyzed local gyrification index (LGI) in 206 participants (ages 5-18) from 14 sites within the ENIGMA Pediatric msTBI Working Group. Vertex-wise regression revealed that longer time since injury (TSI) was associated with increased gyrification in the right fusiform gyrus and multiple left-hemisphere regions, suggesting region-specific neuroplasticity. Contrary to expectations, higher GCS scores …

Fremont Human Remains In Sevier County, Alexis Maughan

Theses and Dissertations

This study examines Fremont mortuary practices in Sevier County, Utah, through a systematic analysis of 50 individuals, recovered mainly from Late period sites. While Fremont burials are typically described as highly variable, the Sevier County sample reveals a striking pattern: approximately half of the individuals exhibit evidence of processing and were left scattered on structure floors rather than being intentionally buried. This pattern stands in contrast to the widely accepted description of Fremont burials as consisting mainly of individuals buried separately in expedient pits with minimal grave goods. The analysis draws on previously published reports, compiling the available data on …

Assessing The Impact Of Internal Flow Dynamics On Detection Region Concentrations Of Low-Cost Optical Particle Counters, Livingstone Quarshie

Theses and Dissertations

Particulate matter (PM) poses significant risks to human health and the environment, making accurate measurement essential for exposure assessment and regulatory decisions. While traditional reference methods provide reliable data, they are often bulky, expensive, and difficult to maintain. Optical Particle Counters (OPCs) offer a cost-effective alternative, commonly used in clean rooms, residential spaces, and personal exposure monitoring. These devices rely on light scattering to measure PM concentrations. However, low cost OPCs face challenges related to calibration and measurement accuracy, requiring careful performance evaluation. This study used computational fluid dynamics (CFD) tools, CONVERGE Studio and ANSYS Fluent, to simulate a simplified …

Testing The Feasibility, Acceptability, And Preliminary Impact Of A Brief Behavioral Sleep Intervention To Improve School-Aged Childhood Sleep Behaviors, Isabella Delores Wright

Theses and Dissertations

Objectives: Parent knowledge of what healthy sleep looks like in their children has scarcely been evaluated, and little is known as to whether improving child sleep through a brief behavioral intervention that emphasizes mastery, personalization, motivation, and modeling will enhance sleep outcomes in children. As a result, we designed this study with the following aims in mind: 1) determine existing parental knowledge of healthy child sleep practices of parents; 2) test the impact of a personalized, brief parental sleep intervention aimed at increasing parental self-efficacy and parent behaviors; and 3) determine preliminary feasibility, acceptability, and impact of this personalized intervention …

Assessing Innovations In Wildlife Monitoring: Estimating Abundance And Inferring Parturition Of Ungulates With Technology, Elicia Cotcher

Theses and Dissertations

Enhancements in technology are creating opportunities for novel methods of wildlife monitoring. Traditional methods of wildlife monitoring are often costly or time-consuming, and new technological advancements such as remote cameras and GPS collars are creating opportunities for exploration as these technologies become more accessible and reliable. We sought to assess the efficacy of two novel methods of ungulate monitoring. The first is an abundance estimation method using remote cameras termed Instantaneous Sampling (IS). IS seeks to estimate abundance using time lapsed remote cameras on a population of unmarked individuals. Our goal was to compare IS estimations against the true observed …

Effects Of Novel Fire Regimes On Plant And Animal Communities, Ryan Pienaar

Theses and Dissertations

Human actions are threatening global biodiversity through changes to ecosystems to which species are not well adapted. One of the main pathways by which humans affect change is through altered disturbance regimes. This includes changes in the size, frequency, and severity of wildfires. The impact of wildfires on native plant and animal communities varies across ecosystems as species in a community have adapted relatively predictable fire patterns over time. Changing fire patterns alters successional dynamics that can favor certain species over others and thus have a negative impact on biodiversity. This dissertation evaluates responses of different plant and animal species …

Methamphetamine Effects On The Striatal Neuroimmune System, Hillary Adelaide Wadsworth

Theses and Dissertations

Dopamine is thought of as the reward molecule of the brain, and while it does deal with reward, it is also associated with motivation and crucial for controlled movement. There are two main dopaminergic systems in the brain, the nigrostriatal system, which originates in the substantia nigra compacta and projects dopamine into the dorsal striatum; and the mesolimbic system, which originates in the ventral tegmental area and projects dopamine into the nucleus accumbens. While the mesolimbic dopamine system deals with motivation and reward, the nigrostriatal pathway underlies movement. Microglia are the immune cells of the brain and are incredibly dynamic. …

Maximizing Germination Of Three Native Plants For Rangeland Restoration And Urban Landscapes Through Seed Enhancements, Janetta Teichert

Theses and Dissertations

Native plants offer numerous ecological benefits and opportunities for both rangeland restoration and urban landscaping, making their integration essential for building sustainable ecosystems. They enhance soil health, promote pollinator activity, increase microbial diversity, and support both wildlife and livestock, all of which contribute to overall ecosystem resilience. A promising strategy to improve the use of native plants is the application of seed enhancement technologies, which can optimize seed germination, improve seedling establishment, and enhance overall plant success in challenging environments. These post-harvest seed treatments incorporate materials that improve seed performance, often through coatings composed of binders, fillers, and active ingredients. …

Inquiry-Style Planetarium Activities, Emma Rasmussen Groberg

Theses and Dissertations

Introductory astronomy students often face challenges in exploring their own ideas and investigating astronomical phenomena due to the limitations of nighttime observation and weather conditions. Planetariums overcome these barriers by simulating the night sky, making it accessible during class sessions regardless of external conditions. This provides an opportunity to engage students in inquiry-based activities, where they are presented with a scenario and encouraged to use their own reasoning to reach conclusions. In this study, we implemented inquiry-based activities in PHSCS 127 using the planetarium as an investigative tool. We developed four activities designed to help students explore their ideas and …

Organismal Classification And The Phylogenetic Tree: Improving Its Teaching Using Decision-Based Learning, Melissa Cavan

Theses and Dissertations

For a lot of students, learning biology is like learning a new language. There are new terms and concepts that a lot of new students have never heard of. Evolution is the cornerstone for understanding biology, yet it is one of the more misunderstood topics. In combination with learning new terms and concepts some students come in with preconceived ideas about evolution or misunderstandings about how evolution and the phylogenetic tree work. The research indicates instructors attempting active learning techniques to increase understanding of the phylogenetic tree with mixed results, where there appears to be some improvement but nothing significant. …

"The Truth Of Our Historic Encounter": Curating Networks Of The Past In Colson Whitehead's The Underground Railroad, Holden O. D'Evegnee

Theses and Dissertations

What unites the critical response to Colson Whitehead's 2016 novel The Underground Railroad is universal interest in the text's attitude towards historical truth. I contend that critics fixate so much on the issue of truth that they miss how the novel offers an alternative to historic truth in the form of an aesthetic encounter. During her employment as a "living exhibit" in North Carolina's Museum of Natural Wonders, protagonist Cora despairs at the apparent absence of truth. Despite the overt manipulation of history to justify white imperialism in the museum, Cora experiences a transcendent moment of refuge when she works …

Genetic Regulation Of Anthocyanin Biosynthesis In Flower Color In Gilia, Veronica Mosquera

Theses and Dissertations

Gilia was the model species in this research to study the genetic regulation of flower color. I generated an F2 population from a cross of two closely related leafy-stemmed Gilia: G. capitata with blue and G. yorkii with white flowers, to obtain the fertile F1, which was selfed. The F2 population showed a segregation ratio between pigmented versus white flowers 3:1, suggesting a single locus with a major effect on the regulation of flower color. Then, the G. yorkii genome was assembled and annotated to become the reference genome to genotype-by-sequencing (GBS) 189 F2 individuals. The Quantitative Trait Loci (QTL) …

"Peace [That] Could Only Be Amazement, Too": Narrativizing Wonder And Strangeness In Marilynne Robinson's Lila, Tricia Cope

Theses and Dissertations

Set against the backdrop of the mid-twentieth century American Midwest, Marilynne Robinson's Lila is a profound story of loss and redemption told through the perspective of a young woman who emerges from a childhood of trauma and neglect and begins a new life in the quiet town of Gilead, Iowa. This paper examines the novel as a narrative meditation on the theological and ontological dimensions of wonder. While its fragmented structure and bleak subject matter have led some critics to interpret the novel as emotionally fractured or pessimistic, I argue that its recursive form and narrative disorientation are deliberate formal …
